Embodied Meaning in Comprehending Abstract Chinese Counterfactuals

Embodied cognition theories propose that language comprehension triggers a sensorimotor system in the brain.However,most previous research has paid much attention to concrete and factual sentences,and little emphasis has been put on the research of abstract and counterfactual sentences.The primary challenges for embodied theories lie in elucidating the meanings of abstract and counterfactual sentences.The most prevalent explanation is that abstract and counterfactual sentences are grounded in the activation of a sensorimotor system,in exactly the same way as concrete and factual ones.The present research employed a dual-task experimental paradigm to investigate whether the embodied meaning is activated in comprehending action-related abstract Chinese counterfactual sentences through the presence or absence of action-sentence compatibility effect(ACE).Participants were instructed to read and listen to the action-related abstract Chinese factual or counterfactual sentences describing an abstract transfer word towards or away from them,and then move their fingers towards or away from them to press the buttons in the same direction as the motion cue of the transfer verb.The action-sentence compatibility effect was observed in both abstract factual and counterfactual sentences,in line with the embodied cognition theories,which indicated that the embodied meanings were activated in both action-related abstract factuals and counterfactuals.

Motor Compatibility Effect on the Comprehension of Complex Manual Action Sentences in L2:An ERP Study

Embodiment theories proposed that the comprehension of language involves sensory-motor simulation in the brain.The present study examined the brain response to motor compatibility effect in comprehending action-related linguistic materials for participants learning Chinese as a second language(L2).In this study,participants are required to read action-related sentences describing an agent performing two manual actions simultaneously or sequentially by manipulating temporal conjunctions.The sentences with simultaneous actions are marked by Chinese parallel structure一边……一边……(“while”)showing non-congruent motor condition while the sequential action sentences are marked by先……然后……(“after”)showing congruent motor condition.Event-Related Potentials(ERPs)were recorded with the second verb phrase.A larger fronto-central late positivity was observed for the sentences with simultaneous actions rather than the sentences with sequential actions due to body constraints,revealing that late L2 Chinese learners integrate embodied knowledge while processing action-related complex sentence despite demanding more cognitive resources,and longer processing time.

Quantitative Evaluation of the Compatibility Effects of Aidi Injection on the Treatment of Hepatocellular Carcinoma Using Targeted Metabolomics:A New Strategy on the Mechanism Study of an Anticancer Compound in Traditional Chinese Medicine

Objective:Compound traditional Chinese medicine(CTCM)with the application of compatibility from multiple active ingredients with multiple-specific targets can achieve a synergistic effect on cancer therapy.This study is aimed to observe the compatibility effects of Aidi injection on the treatment of hepatocellular carcinoma and to explore the mechanism of CTCM.Methods:Aidi injection is a clinical compound prescription containing Mylabris,Ginseng,Astragalus,and Acanthopanax,which can inhibit tumor growth and induce apoptosis.In this study,the anticancer activity of Aidi injection,as well as its disassembled and combined compositions,had been evaluated by varying levels of polyamine biomarkers on human hepatoma Hep-G2 cells detected using ultrahigh-performance liquid chromatography-tandem mass spectrometry.Results:According to the different variations in polyamine levels,it was revealed that Mylabris and Ginseng had an antitumor effect,while Astragalus acted as an assistant and Acanthopanax had weak anticancer activity.The increased level of polyamines in Hep-G2 cells had been found in HL-7702 cells.On combining Mylabris and Ginseng,polyamine levels went close to the normal level,which was even more marked when Astragalus was added.Aidi injection acted like the combination of Mylabris,Ginseng,and Astragalus.Conclusions:This study established a quantitative evaluation of the compatibility effects of Aidi injection based on polyamine biomarkers and evaluated the consistency of its anticancer effect,providing a manner to research the efficacy evaluation of CTCM.Moreover,the correlation between polyamine metabolism and anticancer activity can be used in anticancer drug screening.

Objective To observe the preventive effect of different compatibilities of Ramulus Cinnamomi(RC)and Radix Paeomiae alba(RPA)in Guizhi Decoction(GZD)on neurotransmitters and their rate-limiting enzymes,and neurotrophic factors of cardiac sympathetic denervation model rats induced by 6-hydroxydopamine(6-OHDA).Methods Totally 54 male Wistar rats were randomly divided into 6 groups,i.e.,the blank control group。

Study on deformation mechanism of Ti-2Al-2.5Zr alloy tube in the flattening test

The flattening test,using one pair paralleled plates to flatten tube structure radially,is generally employed to examine the ductility of tube used in once through steam generator(OTSG).This study focuses on the stress condition and deformation mechanism analysis on the concentrated stress regions of Ti-2 Al-2.5 Zr alloy tube during the flattening test.Firstly,the finite element analysis was performed using the commercial software ABAQUS to determine the stress condition.Secondly,the Electron BackScattered Diffraction(EBSD)was implemented to observe the microstructure evolution of Ti-2 Al-2.5 Zr alloy.Finally,Schmid law was employed to analyze the activated deformation mechanism under condition of the complex stress.It was found that the condition of the complex stress in stress concentration regions,including tension and compression regions,can be simplified into two directional stresses condition.In grains whose c-axis is nearly towards TD and ND,the strain is mainly accommodated by prismatic slip,whereas in grains whose c-axis deviates about 45°from ND to TD mainly by basal slip.The{10-12}extensive twin and corresponding parent grain orientation mainly relied on the stress condition.Additionally,the intergranular twin pairs connected at common grain boundaries(GBs)with high strain compatibility were found at low angle GBs,which were activated under a combination of macro stress and strain compatibility effect.
